Abstract:
Quantitative trait locus (QTL) genetics retains an impor-
tant role in the study of biological and agronomic process-
es; however, its genetic resolution is often comparatively
low. Community-based strategies are thus required to
address this issue. Here we detail such a strategy wherein
the widely used Solanum pennellii introgression lines (ILs)
in the genetic background of the cultivated tomato (Sola-
num lycopersicum) are broken up into molecular marker-
defined sublines as a community resource for map-based
cloning.
